Perhaps you should try some spelling variations:
"modified parameter optimization algorithms" » "modified parameter optimisation algorithm", "modified parameter estimation algorithms", "modified parameter estimation algorithm", "modified parameter optimisation algorithms", "modified parameter estimation algorithmss", "modified parameters optimization algorithms"
"designed network optimization algorithm" » "designed network optimisation algorithm", "designed network estimation algorithm", "designed network estimation algorithms", "defined network optimization algorithm"

You may be able to get more results by adjusting your search query.

• The words AND, OR and NOT may confuse the search; try adding quotes: "((\"designed network optimization algorithm\") OR (\"modified parameter optimization algorithms\"))~".
• Removing quotes may allow a broader search: (( designed network optimization algorithm ) OR ( modified parameter optimization algorithms ))~.
• Adding a wildcard symbol may retrieve word variants: (("designed network optimization algorithm") OR ("modified parameter optimization algorithms"))*.
